pressure label lists the recommended cold
tire i nflatio n pressures for the vehicle at its
maximum capacity we ight a nd the tires that
were on your vehicle at the time it was man ­
ufactured . For recommended t ire pressures
for normal load condit ions, please see chap ­
ter ~
page 2 78 .
-Turn the valve stem cap counter-clockwise
to remove it from the tire valve .
- Place the air pressure gauge on the valve.
- The tire pressures should only be checked
and adjusted when the tires are cold . The
s light ly raised pressures of warm tires must
not be reduced .
- Adjust the tire pressure to the load you are
carrying.
- Re insta ll the va lve stem cap on the valve .
When should I check the tire pressure ?
The correct tire pressure is especially impor ­
tant at high speeds . The pressure sho uld
therefo re be checked at least once a month
and a lways before start ing a journey. Do not
forget to check the tire pressure for the spare
wheel.
When should I adju st the tire pre ssures?
Ad just the tire pressure to the load you are
carrying. After changing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels. In addition, you must then
store the new tire pressures i n the t ire pres­
sure mon itor ing system
~ page 294.
A WARNING
Incorrect tire pressures and/or unde rinfla­
tion ca n lead sudden tire failure, loss of
cont ro l, col lision, ser ious persona l inju ry
or even death.
- Whe n the wa rning symbo l

the instrument cl uster, s top an d inspect
the tires.
- Incorre ct tire pressure and/or unde rinfla­
t ion can cause inc reased t ire wear and
can affect the handling o f the veh icle and
stopp ing ability.
- Incorrect tire pressures and/or underin­
flation can also lead to sud den tire fa il-

flation, ca using loss of veh icle contro l.
- The driver is responsib le for the correct
tire pressures for all tires on the veh icle.
The applicable pressure values are locat­
ed on a sticker o n the dr iver's s ide B-pil­
lar .
- Onl y when all tires on the vehicle are fil­
led to the correct pressure, the t ire pres­
sure mon itor ing system can work cor­
rectly .
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage .
Therefore it is ess ential that th e drive r
observe t he spec ified t ire p ress ure val ues
for the tires and the cor rect pressures for
the func tion of the t i re p ress ure moni to r­
ing system.
- Always in flate tires to the recommen ded
a nd correct t ire p ress ure be fore dr iv ing

- D riving with unde rinf lated tires bend
mo re, letting them get too hot resulting
in tread separation, s udden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat b uild- up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the t ires will wear prematurely and the
veh icle w ill not handle well.
- If the tire is not flat and you do not have
to change a wheel immediately, d rive at
red uced speed to the nearest service sta­
tion to check the t ire press ure and add
air as requ ired .
(D Note
Driving w ithout valve stem caps can cause
damage to the tire valves. To prevent this,
a lways make sure that factory installed
valve s tem caps o n all whee ls are sec urely
mounted o n the valve .
@ For the sake of the environment
Underinflated tires will also increase the
fuel consumpt ion.

TPMS malfunction indicator is combined with
the low tire pressure tellta le . When the sys·
tern detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This se·
quence will continue upon subsequent vehicle
start-ups as long as the malfunction ex ists .
When the malfunc tion indicator is illuminat·
ed, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunct ions may occur for a variety of rea·
sons, including the installation of replace·
mentor alternate tires or wheels on the vehi·
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re­
p lacement or alternate tires and wheels allow
the TPMS to continue to function properly.

308 Emergency situations
Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who
have the necessary tools and equipment to perform these operations.
Starting by pushing or
towing
Q;) Note
Your vehicle is equipped with an automatic
transmission. Consequently, the engine
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
gine .
Jumper cables
Use only jumper cables of sufficiently large
cross section to carry the starter current safe­
ly. Refer to the manufacturer's specifications.
Use only jumper cables with
insulated termi­
nal clamps which are distinctly marked:
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield your eyes and avoid lean­
ing over the battery whenever possible. -
A discharged battery can freeze at tem­
peratures just below 32 °F (0 °C). Before
connecting a jumper cable, you must
thaw the frozen battery completely, oth­
erwise it could explode.
- Do not allow battery acid to contact eyes
or skin . Flush any contacted area with
water immediately .
- Improper use of a booster battery to
start a vehicle may cause an explosion.
- Vehicle batteries generate explosive gas­
es . Keep sparks, flame and lighted ciga­
rettes away from batteries.
- Do not try to jump start any vehicle with
a low acid level in the battery .
- The voltage of the booster battery must
also have a 12-Volt rating. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged bat­
tery . Use of batteries of different voltage
or substantially different "Ah" rating
may cause an explosion and personal in­
jury.
- Never charge a frozen battery. Gas trap­
ped in the ice may cause an explosion.
- Never charge or use a battery that has
been frozen. The battery case may have
be weakened.
- Use of batteries of different voltage or
substantially different capacity (Ah) rat­
ing may cause an explosion and injury.
The capacity (Ah) of the booster battery
should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
page 248, Engine com­
partment.
@ Note
- Applying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
control units, relays, radio, etc.
- There must be no electrical contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
positive(+) terminals are connected. ..,.

@ Tips
-The discharged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump start ing or charging the
battery, never connect the negative
ground cable to the battery negative
post because the battery manager sys­
tem must be able to detect the battery's
state of cha rge. A lways connect the neg­
ative g round cab le to the negative
gro und post o f the battery manage r con­
trol uni t.
Use of jumper cables
Make sure to connect the jumper coble
